We ran the web sdk sample (CDN based version) and we get error ERR\_CERT\_COMMON\_NAME\_INVALID. We are seeing this in all kind of browsers (Chrome, Safari, Edge, etc). **Error** jquery.min.js:2 GET [https://rwcprod.zoom.us/wc/ping/94986093221?ts=1597961716757&auth=UBIJDn4HPqjoBbwB-QrzZOBSH2-w-DR7oLQ-FnQvmQU&rwcToken=L4EiMmG4UBc3Exn8DV1XGCDzWLSonU0O76QpIqhazig&dmz=1&\_=1597961716260](https://rwcprod.zoom.us/wc/ping/94986093221?ts=1597961716757&auth=UBIJDn4HPqjoBbwB-QrzZOBSH2-w-DR7oLQ-FnQvmQU&rwcToken=L4EiMmG4UBc3Exn8DV1XGCDzWLSonU0O76QpIqhazig&dmz=1&_=1597961716260) net::ERR\_CERT\_COMMON\_NAME\_INVALID **Which version?** We are using the Zoom Web Sdk version 1.7.10 from the CDN. **To Reproduce(If applicable)** Steps to reproduce the behavior: 1. Download the zoom web sdk version (latest) 2. Run it in any browser like Chrome 3. You will get the error **Additional context** When we run the sample app the audio is very bad, so we dont know if this error could be related. Do you have any idea if this error is relevant, and also if there is a way to correct it or hide it. Also in your code, we have this function commented, because we dont understand if its required ZoomMtg.setZoomJSLib. Do we need to use this function, I mean if its related with the error? Thanks in advanced ---

Hey @tom3, Does the Web SDK work with this error? > [@tom3](#): > > When we run the sample app the audio is very bad, so we dont know if this error could be related. Do you have any idea if this error is relevant, and also if there is a way to correct it or hide it. We are aware of some audio issues on the Web SDK and are working to fix them. Stay updated here: [https://marketplace.zoom.us/docs/guides/stay-up-to-date/upcoming-changes/web-sdk](https://marketplace.zoom.us/docs/guides/stay-up-to-date/upcoming-changes/web-sdk) > [@tom3](#): > > Also in your code, we have this function commented, because we dont understand if its required > ZoomMtg.setZoomJSLib. Do we need to use this function, I mean if its related with the error? The `setZoomJSLib` function is for customizing the path to where the Web SDK files are. You can see an example of it being used here: > **[@zoomus/websdk](https://www.npmjs.com/package/@zoomus/websdk#usage)** > > Zoom Web SDK. Latest version: 2.18.2, last published: 10 days ago. Start using @zoomus/websdk in your project by running \`npm i @zoomus/websdk\`. There are 4 other projects in the npm registry using @zoomus/websdk. Thanks, Tommy ---

Hi Tommy: Because this error is not related with the sound quality, we will wait for your next version, because right now users are not accepting the zoom quality of the embedded version. Thanks ---
